Mecmesin Solutions for the Electrical and Electronics Industries

Mecmesin force and torque systems are very versatile for testing a wide range of electrical and electronic applications. From circuit-board flexure to component shear-off force, and from rotary switch actuation torque to membrane-control pressures, we can provide design and quality control systems to ensure compliance with specification and standards. Our Emperor™ control and analysis software can integrate switching events, or assess mechanical strength to break, as in wire terminal strength pull-off tests.

Whatever your needs in electrical and electronic force or torque, from power transmission down to micro-circuitry, there is a suitable Mecmesin tester.

Wire and cable

Affordable testers and expert service, for wire and cable

The tensile strength and yield point determination of wires and cables is determined by a straightforward tensile test. Rating a cable to its required load, without over-specification is important for keeping weight and material costs down. Whether a fine medical guidewire or a construction cable, testing to assure conformance to specification is essential. Mecmesin MultiTest tensile testers are available up to 50 kN, and fine wires can be measured on our low-end models below 500 N.

Wire terminals, terminators and connectors

Wire terminals, terminators and connectors

Mecmesin wire terminal strength testers are widely used for versatile and rapid pull testing of standard crimps and welded wire joints and nuggets. Standard and customised fixtures can be provided, with budget machines through to fully programmable touch-screen systems. The same Mecmesin tensile testers can be used to test wire strength, insulating sleeve pull-off and many other related tests.

Electronic components and assemblies

Affordable testers and expert service, for electronic components and assemblies

Is your brand reliant on third party electronics, or do you need to know that your own components will withstand prolonged use? With your own tester, you can help protect your reputation for quality.

Electronics components and assemblies are found in the most demanding environments, and despite massive integration and sub-miniaturisation, require physical testing. This includes measuring the shear and pull removal forces from printed circuit boards, the flexural properties of the boards themselves, the peel resistance of conductive tracks, and the precise torque of the lightest rotary controls and presets. Mecmesin testers can be used to apply your own or industry standards, in an accurate and repeatable manner, either in design or post-production quality assurance.

Electrical switches

Affordable testers and expert service, for electrical switches

A switch that fails to turn off can be more dangerous than one that fails to turn on. How do you test your switches for ease of use, reliability and quality of construction?

Mecmesin testers, driven by Emperor™ control software, can measure not only the force required to operate a switch, but profile the whole action for positive response, undue friction, or defects. Continuous cyclic tests for component wear can also be done, and, as in the case of push-to-break switches, the electrical connection itself can be used as an event in the test program. For simple rotary switches, manually-operated digital torque testers may be appropriate, whereas for compression tests of rocker switches or membrane switch buttons, a MultiTest is ideal.

Glass and ceramics

Affordable testers and expert service, for glass and ceramics

How tough is your toughened glass? How much force can your ceramic floor tiles take? Or how high do you stack your bottles? Is that new jar design as strong as the last? A computerised compression testing system will tell you, accurately, every time.

Though stronger than plastic containers, glass is also heavier, and the same requirement applies, to balance weight and strength whilst optimising material thickness. Whilst a PET bottle will ‘give’ under top-load, glass failure is catastrophic. Testers with higher crush capacity and safety enclosures are therefore required. Ceramic materials and glass panels are tested for their flexural strength and breaking point, using three-point bend fixtures. For all these applications, Mecmesin MultiTest universal testing machines provide an ideal solution.

Magnets and solenoids

Affordable testers and expert service, for magnets and solenoids

New high-strength magnets have taken over in the home, office and in clothing and jewellery, where adhesives or mechanical studs used to be. Unlike poppers and clips, they require no force to attach, but have you selected the right magnet? How do you test for this? Neodymium magnets are also widely used as fasteners for bags, jewellery and clothing, and here the pull strength must be strong enough for retention without damaging the items they secure when pulled apart.

Testing the design and suitability of electromagnets, relays and solenoids can also include the application of different electrical inputs, to determine performance through the complete travel of moving parts. This profile of magnetic devices is vitally important for accurate and predictable behaviour. A Mecmesin MultiTest tensile tester with Emperor™ control and analysis software will provide a complete picture of the forces over distance in magnetic and electromagnetic devices, as well as applying a wider range of tension or compression tests on the assemblies where they are in use.

Manual controls and switches

Affordable testers and expert service, for manual controls and switches

Does it twist, slide or press as designed, and is this a subjective impression? Or have you tested your controls against objective criteria, using an accurate programmable test system for repeatable testing?

Manual controls, pedals and switches are designed for positive or smooth action and ease of use. Human forces or effort applied to foot- or hand-operated equipment in normal use are used to derive test programs based on an expected range of forces.

These objective measures can be used to ensure over-application of force does not break a control, or lead to malfunction. Mecmesin MultiTest force test systems with Emperor™ control software provide the required repeatability and accuracy for production line quality control as well as for design, to show not just operating force, but any lack of smoothness or overtravel, which may indicate manufacturing problems. Hand-held digital instruments from Mecmesin are also widely used to measure operation of controls in situ, rather than as a component bench test.

Plastic components and subassemblies

Affordable testers and expert service, for plastic components and subassemblies

The only way to test the resilience of many products is to subject them to forces beyond specification, as complete assemblies. It is one thing to test component parts, but how they interact in a complex assembly can be less predictable. It may be the integrity of the item that requires being pulled, pushed or twisted, or a moving part needing to be taken to extremes, but it is the working of the whole together that needs testing.

Does one part distort or break first, and what does this lead to as a consequence? Mecmesin MultiTest tension and compression testers can apply forces from less than 1 kN up to 50 kN. The Emperor™ control and analysis software provides fully-programmed repeatable testing, with complete detail in the response of the assembly to the applied forces. The same tester can be used in tension of compression to apply a variety of tests, with programs recalled at the touch of a button.

Pressure sensitive adhesive tapes and labels

Do your customers stick with you? Routine quality testing of your tapes and labels for peel, stretch and tear will help ensure they do.

Pressure sensitive adhesives may be required for a very strong fixing, or to be peeled for opening and resealing. Some may be used for security and must result in the destruction of a label, for example, if peeling is attempted. Standard methods set by PST, Afera and ASTM for PSA tapes and labels are commonly used.

These define the sample preparation and mounting method, the type of peel test applied, and require standard test equipment for maximum repeatability. Mecmesin MultiTest systems are an affordable and versatile solution to all your peel test requirements.

Seals and seams

Affordable testers and expert service, for seals and seams

Seals and seams, whether elastic, adhesive or welded, are designed to hold under various forces that may drive or pull them apart. Failure may be due to internal pressure, peeling or tensile shear. Some seals are designed to fail at a given force, either for opening or to release pressure for safety. In all cases, the point of failure is important, and for all test types there is a suitable Mecmesin MultiTest, computer-controlled for repeatable testing at the touch of a button. Routine testing of seal strength is a vital part of quality assurance, and is best done at the point of production.
